Specification of Letters Patent.

Patented May 28, 1907.

Application filed Hay 5, 1906.v Serial No. 315,386.

To a/ZZ whom, it may concern.-

Be it known that I, JOHN Z, a.

citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Pile'Fabric, of which the following is a specification. In my prior patent No. 813,131, atented February 20, 1906, I` have descri d and claimed a novel construction of a pile fabric in which the combined pile and warp thread is employed and in which the pile Warp at stated intervals, while forming pile,Y passes around one of the wefts of the outer plane before it passes to the inner weft of the opposite plane. I

My invention consists ol' a novel construction of woven pile fabric in which the coinbined pile and binding warp is employed in Such a manner that when making pile it is assed around the inner wett only of the difierent cloths and is passed around the wetts of the outer plane only when a dii'ferent pile warp is employed forming the pile:

Figures 1 and 2 represent longitudinal sections of a pile fabric embodying my invention with the binding warps omitted for clearness of illustration. Figs. 3 and 4 re resent longitudinal sections of the complete fabric as respectively shown incomplete in Figs.1

nd 2. Y a Similar numerals of reference indicate corresponding parts in the iigures.-

Referring to the drawings 1 designates Ya. ile W which when used for ma pile, is passe over the Wefts 2 in the upper c oth 3 and under the weft 4 in the lower cloth 5. This o eration may. be repeated during-any desire number of picks. c o

-When the pile warp .1 is no longer-employed-in ma pile it is assed over one of the wefts 6 in t e outer p ane and another pile warp as. 7 is brought'to the inner weftsand passes around the same in order to form that these operations may be repeated during an desired number of picks in Fig. 1 ,g have shown the pile Warp itis employed for .making pile, as being passed 5oV alternately over and under the weft 6 in the outer plane, it thusbeing seen that .in each instance the warp when ma pile is never employed as a warp an never passes beyond the inner weft until another -pile warp is employed and begins making pile, at which time the iirst mentioned pile warp is pased to the oiter weft and serlyes as a in er w an gurin war ,f ein returned, vlliiin desired, tg ma e g passed around the inner wei'ts. pile warp 1 is not to be used as a pile warp or any number of icks it is passed alternately above and bellow the wefts 6, as seen in Figs. 2 and 4. It stood, when this operation is taking place with respect to the pile warp 1 or the warp 7 that other w s are being employed for making pile. alghen employed in this manner the warps 1 or 7 act as a igure and binder warp for the outer weft plane or the back of the cloths and adds to the artistic finish of the fabric. It will be seen further that by reason of thel em loyinent of the pile warp to make the pile only when so desired, in. lieu of serving as a binder and figuring war at the same time, the back of the fabric w show a pattern which is desirable.

,8 designates a stufferor body warp which lies between the wefts 2 and 6, in the upper cloth 3, and 13 designates the stuiler or body w which lies between the wefts 4 and 12 inaie lower cloth 5. The object of using the stuifer warp is to form two weft lanes for the purpose of not only giving stabty to the fabric but since the said stuifer warps'in each of the upper and lower cloths pass in a straight line through the same inthe iinished article, it will prevent stretching, which might otherwise occur, since the other binding threads pass through the weft planes atan le.

. In Fig-2 the pilejw s 9, 10 and 11, when m pile, are passe Vover the wefts 2 in the upper cloth and nnder the wefts 4 in the' ile and hen the Vlower cloth during any desired number of picks, butA when any are not used for making pil'e they are passed alternately over and un# Ader the outer weft 12 and thus serve as a bindin' g and gun `ng warp for the outer weft planes, the saine as already described with resipec' ttothewarps1and7. Y

t will be observed that the threads 1 and 7 are shown in 1 as being combined pile, binding 'a'nd g warps passing over and under the weft threads 6 and extending c through the fabric as iles in `such a mannerthat when the fabric is cut their extremities will, of course, be underwill form pile ends from threads. and 11, being there binding and figuring warps for outer wefts 12, while in Fig. 2, showing another section of-the fabric, these warps 1 and 7 form binding and figuring warps, uniting the wefts of the outer plane, while the ile warps for both sides of the double pile fa ric are in this case furnished from the opposite side by warp threads 10 and 11. The piles are thus woven from either side, at 'will while the inner and outer planes of wefts are united by additional warp threads in groups of two and one the relation borne by the number of wefts in the inner plane to the wefts in the outer plane. Thus portions of the pile fabric upon each side are or may be united as to their inner and outer planes of weft threads by this additional binding warp or series of binding warps alone or by both the Y binding warp and the combined pile, binding and iiguring warp.

It is evident that, if desired, any ofthe warps 9, 10 and 11 may be retained between the wefts 4 and 1'2 for any desired number of picks, so that said warps will appear neither in the pile warp nor on the back of the fabric, as will be apparent with regard to the warp 9 in Figs. 1 and 3 land it is evident that when desired said warp 9 may be caused to answerl both as a pile warp and as binding and figuring warp in a manner similar to that described in connection with the other pile warps herein referred to.

14 designates the binding warps'which are em loyed to 4tie or. bind the weft and warp toget er, said binding warps passing over two of the inner weft threads and one of the outer weft threads, Wherebv'in each vshed are two inner weft threads and one outer weft thread,

the pile warp being passed laround a single inner weft thread and the binding warp .serving to draw the two inner weft threads together with the outer weft threads in con- ]unction with Vthese inner weft threads, so that three weft threads are tightlyvbound together in each shed of the binding warp, the object of this construction being to pinch the pile warps, betweenthe three wefts between each`crossing of the binder was, so that the pile when cutwill be firmly ound in the ack, preventing theV pulling out. When the pile Warps 10 and 11 are not to appear in the pile during several consecutive picks, said warps are passed alternately above and below the weft 12, as seen in Figs. land 3. The pile is cut in the usual way during the recess of weaving or this may be done out of the loom with a machine s ecially con-l structed for this purpose, so that two dis; tinct fabrics are produced when the cutting is effected.

It will now be apparent to those skilled in the art that I have in the resent instance produced Ia novel and useful) constructon of woven pile fabric which differs from my prior atent heretofore referred to in the manner 1n which the combined pile and binding warp is employed, said warp'in my present conf.

struction making pile passing around the inner wefts 2 and 4 only and assing around the weft of the outer plane o y when a differ.- ent pile warp is employed in forming the ile',

thus forming a igure at the back o f the c oth. A

It will be apparent that a great saving in material is brought about by the use of my present invention, since the pile warp when used in making pile simply asses around the inner weft threads of each c oth-and does not pass around a weft thread of the outer cloth during the forming of the pile, as in my prior atent, and furthermore I am enabled to havl the design produced on thevback of the clot 'It will .be further apparent from the fore-Y going that I have produced a novel and useful construction of a pile fabric and while I have in the present instance shown and describedthe preferred embodiment thereof, it is. to be understood that it issusceptible of modification in various particulars without departing from the spirit and sco e of my invention or sacrificing any of its a vantages.
